HINGE.

Application filed February 16, 1912.

To all whom t may concern:

Be it known that we, JOHN LA VERGNE, residing at Newark, and GASPAREIzzo and FERDINANDO MAcoLrNo, residing at Jersey City, in the countiesof Essex and Hudson, respectively, and State of New Jersey, citizens ofthe United States, have invented certain new and useful Improvements inHinges; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to gures of reference markedthereon, which form a part of this specification.

This invention relates to an improved hinge which has a verticallydisposed pintle, the hinge leaves being provided with knuckles whichembrace the pintle, the pintle being supported by the knuckles of one ofthe leaves, and the knuckles of the leaves having inclined faces so thatthe hinge leaves will be moved in the direction of the downward tendencyof the inclined faces, this being preferably in the direction of theclosed position of the leaves whereby the element hung on the leaf isnormally swung shut, although it is evident that the oppositedisposition of the inclined faces can be made so as to normally swingthe element supported by the hinge to an open position.

The invention is further designed to provide a device of this kind inwhich the contact of the inclined faces can be adjusted. In other words,the inclined faces do not engage until the swinging leaf is partly swungopen so that the closing tendency is not operative to a full closing ofthe leaves, but stops when the hinge leaves rotate enough to bring theinclined faces out of contact.

The invention is illustrated in the accompanying drawing, in whichFigure 1 is a perspective view of a hinge fastened to a support and alsoto a supported element, this view showing the adjustable feature. Fig. 2is a face view of the hinge shown in Fig. 1, with the lower knuckleshown in section.

10 is a suitable support such as a doorcasing, and 11 is a supportedelement, such as a door. To the support 10 is fastened the hinge leaf 12which in this specification we call the fixed leaf, this leaf having aknuckle 13 and a knuckle 14 through which passes a Specification ofLetters Patent.

pintle 15 which is fastened to one of the knuckles, preferably theknuckle 13, by a pin 16, which pin prevents the movement of the pintlelongitudinally and also prevents its rotation The swinging leaf 17 whichis fastened to the element 11 has a knuckle 1S resting on the knuckle 14of the fixed leaf. The o pposed faces 19 and 2O of the leaves 1S and 14-respectively, cause the swinging leaf to rise when it is swung to itsopen position, and cause the swinging leaf to close by its own weightwhen it is released on account of the inclined faces co-acting to forcethe descent and consequently the closing of the swinging leaf.

The bottom eye 21 of the swinging leaf fits around a screw-threadedextension 22 of the pintle 15, and a nut 23 screws on the screw-threadedextension, and when it is screwed up it causes the swinging leaf to beraised, that is, its weight is placed on 'the nut 23. When the swingingleaf is raised the inclined faces do not engage unless the swinging leafis swung from its normal position for a slight distance, in fact, if thenut is screwed up far enough, the inclined faces can be held against anyengagement and the inclined faces would not act. 1f the nut is screwedup enough to raise the swinging leaf so that the inclined faces will notengage until the hinge is half way open, the door or other elementsupported on the swinging leaf will not be swung more than half wayshut, and in this way we regulate the swinging of the door.

Having thus described our invention, what we claim is 1. A hingecomprising a fixed leaf having knuckles thereon, a pintle secured in theknuckles, a swinging leaf with knuckles embracing the pintle, the pintlebeing vertically disposed, the knuckles of the movable leaf resting onthe knuckles of the fixed leaf, the supporting surfaces of the knucklesbeing inclined to normally force the leaves to close, and means forraising the movable leaf so that the inclined faces of the knuckles donot abut.

2. A hinge comprising a fixed leaf having knuckles thereon, a pintlesecured in the knuckles, a swinging leaf with a knuckle embracing thepintle, the pintle being vertically disposed, the knuckle of the movableleaf resting on a knuckle of the fixed leaf, the supporting surfaces ofthe knuckles being inclined to normally force the leaves to close, andadjustable means for moving the movable leaf so that the inclined facesof the knuckles can be moved from each other various distances.

tudinal movement in a downward directionh the lower eye of the fixedleaf having an inclined upper face, a swinging leaf with av knucklethereon, the eye of the swinging leaf having an inclined face to act 0nthe inclined face of the eye of the fixed leafa a 15 screw-threadedextension on the pintle, and a nut on the extension, said nut actingwhen rotated on the screw to bear on the eye of the swinging leaf toraise the swinging leaf.

In testimony that we claim the foregoing, 20 we have hereunto set ourhands this 13th day of January 1912.
